. JS'PSIFICATION@xorming part of Letters Patent No. 321,754, dated July'7, 1883. Application filed November 13, 1853. (No model.)

To @ZZ whom it may concern.-

Be it known that l', HERMAN Prs'roRiUs, of Saginaw, in the county ofSaginaw and State have invented certain new and useful Improvements inInvalid-Beds; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the arl: to which it pertains to make and use the same.

My invention relates to invalidbeds, the primary object being to providea bed with devices whereby a patient may be raised without discomfort orliability to injury.

A further object of the invention is to provide means for lifting thehead and upper portion of the patients body at will.

A further object of the invention is to provide a bed with a sheet ofpeculiar construcltion, whereby the calls of nature may be eonvenientlyattended to wit-lient thefremoval of the patient from the bed. l

The invention consists of the improved devices, hereinafter fullydescribed, and pointed out in the claims, for raising and lowering thepatient upon the bed.

The invention further consists in the iinproved evacuationsheet, whichobviates the necessity of removing the patient from the bed.

The invention further consists in the means, hereinafter fully setforth, for raising and securing the head and upper portion of the bodyof the patient in a reclining position.

In the drawings, Figure 1 represents a perspective view of the bedprovided with my improvements. Fig. 2 represents my improvedgrapple-frame. Fig. 3 represents the evacuation-sheet. Fig. 4 representsthe devices for propping up the patient in a reclining position, andFig. 5 is a modification.

A represents a bedstead, which may be of any preferred forni. Brepresents a transverse bar supported above the bedstead by means ofinclined braces C C, whose lower ends are formed with clamps c, forattachment to the side rails of the bed.

D represents a grappling device consisting of the longitudinal rod d,which is upwardly turned at one end. This upwardly-turned end of the rodis secured to a yoke, E, whose ends are formed with hooks e, to engageone end of the sheet F, as clearlyshown in Fig. l.

G and H represent curved arms or yokes,

which are formed with a central sleeve, g, io receive the rod d, towhich said arms or yokes are adjustably secured by means of thumbscrewslz, passing through the sleeve y: The ends of the yokes G and II areformed with hooks o, to engage the edges of the sheet F, as shown inFig. l.

I represents a block-and-taekle device sccured centrally upon the bar Bat one end, and to an adjustable ring, J, secured upon the rod d, at theopposite end. The end of the rope] of the lifting device is secured upona windlass mounted in a yoke-bearing, L, adj usta-bly secured upon therod d by means of the sleeve K and a thumb-screw, Z.

From the construction thus far described it will be apparent that theentire sheet F, upon which the patient rests, may be readily raised fromthe bed, as shown in the patient above the bed when desired.

As shown in Fig. 3, the sheet is formed with an evacuation-opening, M,and with a transverse flap, N, secured at one side of said opening andadapted to pass under said opening, to be buttoned to the under side ofthe sheet, as clearly shown in Fig. The sheet F is also formed above theopening M of two thicknesses of material, the upper thickness, O, ofwhich is adapted to be raised to prop up the patient, as shown in Figs.l and 4.. The sheet F is also provided with any desired number of hooks,o, to facilitate the attachment of the sheet F to the grappling devicel).

P represents a yoke-frame formed at its end with hooks p, to engage thecorners of the upper layer, O, ofthe sheet, and connected by ablock-and-tacklc device, Q, with the transverse bar B. The lifting-ropeIt of the lifting device is used for propping up the patient in areclining position, as shown in Fig. 4.

If preferred, the upper section, sheet F may be supported in its liftedposition by braces S, secured to the side rails of the bcdstead, asshown in Fig. 5; or other devices might be resorted to for supportingthe patient in a reclining position.

The construction hereinbefore described affords a secure and convenientmeans for raising or moving the patient.

I do not limit myself to the precise construction shown and described,but reserve to myself the right to make all such changes in form Fig. l,to suspend O, of the IOC and construction as may properly full withinthe scope of my invention.

Having fully described my invention, what I desire to claim and secureby Letters Patent 1sl. In :in invalid-bed, the combination, with abedstend, of :L transverse bnr and braces for supporting` the latter, aframe suspended from Said bm', and consisting of a longitudinal rod andyokes formed with hooks, lrnd a sheet or hammock suspended from saidframe, substantially as set forth.

2. In an invalid-bed, the combination, with a transverse bar and. itssupporting-braces, of a longitudinal rod suspended from said bar, a.windlass located on sind rod, pulleys secured,

. respectively, upon said bar and rod, :Ln elevating-rope, a hammock,and adjustable yokes supporting the latter, substantially as set forth.

arms or yokes supported upon said bar and 3o' formed with hooks, and a,sheet or hammock Vformed with an opening, as described, amdL with flapsN and O, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subserib- 3, 5 ing witnesses.
